Title: Manufacture of thin-film transistor
Inventor: YAMAUCHI SHINGO
IPC: H01L21/266
Filed: 1992-11-24
Abstract: PURPOSE:To enable the length of a low-concentration impurity region to be constantly equal at both left and right in LDD structure. CONSTITUTION:Phosphor ions are implanted at low concentration onto the upper surface of a semiconductor thin film 2 consisting of polysilicon, etc., with a gate electrode 4 which is provided via a gate insulation film 3 as a mask. Then, a low melting point insulation film 7 consisting of BPSG, etc., is deposited on the entire upper surface and then the surface of the low melt- point insulation film 7 is softened by reflow and is inclined. In this case, the amount of phosphor ion which is implanted into a semiconductor thin film 1 differs depending on the reflow shape of the low melting-point insulation film 7, thus causing nearly outer half of a region which is indicated by a sign 2b of the semiconductor thin film 2 to be an N-type high-concentration impurity region and nearly inner half to be an N-type low-concentration impurity region. In this case, the reflow shape of the low melting-point insulation film 7 can be made equal at the left and right, thus constantly making equal the length of the low-concentration impurity region at left and right.

Title: Developing device
Inventor: YAMAMOTO MASAFUMI
IPC: G03G15/08
Filed: 1987-12-29
Abstract: PURPOSE:To form a uniform and stable toner thin layer on the developer conveyance member and to obtain an image of high quality which has neither ground fogging nor stripe irregularity by prescribing the edge angle of a layer thickness control member on the upstream side of a developer flow at the contacting part between the layer thickness control member and developer conveyance member. CONSTITUTION:The layer thickness control member 4a contacts the surface of a developing roller 2 as the developer conveyance member at a specific angle alpha(110 deg.<=alpha<=170 deg.). When the angle alpha is larger than 170 deg., too large toner layer thickness and a decrease in the quantity of toner electrostatic charging are caused as well the body touching of the control member 4a, and high press-contacting force is required. When alpha is smaller than 110 deg.C, on the other hand, the quantity of toner conveyance is deficient and image density is not enough; and the tip of the control member is easy to damage and a stripe irregularity of an image and an irregularity in density are caused. The angle is controlled to control the contacting of the developer conveyance member with the control member, thereby forming the uniform and stable toner thin layer on the developer conveyance member. Consequently, the image of high quality having neither ground fogging nor stripe irregularity is obtained.

Abstract: PURPOSE:To perform reliable winding by remedying the curve of the starting end of a first guide piece during the initial stage of the feed of a band so as to match with the curvature of a guide piece, and in following, effecting a smooth slide along the guide piece. CONSTITUTION:In the feed of a band D, when the starting end of the band D is moved to a first guide piece 51, the first guide piece 51 is moved forward to a contracted diameter position, and thereafter the first guide piece 51 is returned to an expanded diameter position and the feed of the band D is restarted. This method remedies the starting end of the band D to a curve shape approximately matching with the curvature of the inner peripheral surface of the guide piece 51. In following feed, the starting end of the band D is slid along the inner peripheral surfaces of guide pieces 52, 53, and 54 having the same curvature as that of the first guide piece 51. Thus, the band D is smoothly fed without receiving contact resistance with a small end part C1 of a boot being a substance to be mounted. When the starting end of the band D is moved to an opening part for inserting a band, the guide pieces 51-54 are moved forward to a contracted diameter position, and the band D is wound around the small end part C1.
